Which of the following are NOT regions with high species diversity?
A)
The deep ocean floor
B)
Ecotones.
C)
Peninsulas
D)
Upland tropical forests.

According to the intermediate disturbance hypothesis _____________________.
Question 22 options:
A)
species diversity is highest when disturbance is rare.
B)
species cannot colonize after intermediate disturbance.
C)
competition eliminates species when disturbance is rare.
D)
competition eliminates species when disturbance is common.
Which of the following statement is incorrect about the two broad
classes of explanation of interspecific distribution abundance
relationships?
(a) The first class postulates the existence of a positive feedback
between local abundance and the regional distribution of a
species.
(b) Species that occur in large number across many localities will be
more likely to maintain their wide distribution and high
abundance.
(c) Consequence of positive feedback is that there is no dichotomy.
(d) The consequence of positive feedback is that there is dichotomy,
species will be either widespread or abundant or they will be
restricted and scarce. This division helps in the knowledge and
in turn helps to categorize them accordingly as restricted or
widespread species.

- please explain A drawback of the time hypothesis to explain the variation in species richness is that 1. Cannot account for algal diversity. 2. Fossils do not preserve well in the oceans. 3. Geological activity may interfere with species richness measurements. 4. It is not applicable to marine ecosystems because there was no glaciation in oceans. 5.

- Species have come and gone in response to changing global climates during the history of the earth.

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. (i) Greater species diversity ensures natural sustainability for all life forms. Discuss. (ii) How can the loss of biodiversity be prevented?arrow_forwardEcologists use a rank-abundance curve to display relative species abundance, which is a component of biodiversity. It can also be used to demonstrate species richness and evenness. Figure 1 shows the rank- abundance curve for caddisflies (Order Trichoptera) of two aquatic habitats in northern Portugal (data from L.S.W. Tera). Pollution of streams, on the other hand, reduces the diversity of Trichoptera and several other groups of stream insects, reducing both species richness and species diversity. Interpret why those happened. These rank-abundance curves show that the mountain stream caddisfly community has higher species richness and greater species evenness. 0.1 - Mountain stream 0.01 Greater richness and species evenness 0,001 Coastal ponds 0.0001 20 40 60 80 Abundance rank Figure 1: Rank-abundance curve for caddisflies (Order Trichoptera) of two aquatic habitats in northern Portugal (data from L.S.W.
